I bought this program to help my son, who is at the end of Saxon Calculus in high school (maybe equivalent to Calc II?). I find it increasingly difficult to help my kids at this point and thought I would make my life easier. This program not only does not do trigonometric substitution, as mentioned in a previous review, it also does not apply l'Hopital's rule when evaluating limits. In the one case the problem remains unsolved, in the second case an incorrect answer is given with no indication that it could be incorrect. I entered a third problem from my son's homework and it presented an incomplete answer, refusing to fully evaluate the limit of a natural logarithm. I have not continued to explore for further short-comings since these came up in the second half-hour of using the program.

The first half hour of using the program was a painful exercise in figuring out how to actually use it. It is an extremely clumsy program, having such things as an annoying graphic of a large pencil which obscures parts of the problem and takes a large chunk of screen with it when it moves around. It can only be turned off temporarily. When inserting a symbol, it is necessary to first select insert and then click again on the page. More annoying, it is impossible to place the cursor within a problem by clicking on the spot - the arrow keys must be used.

I suppose I would be able to put up with the with such clumsy annoyances if we actually found the program to be helpful. If your student needs help with very basic calculus, "Calculus Solved!" might be worth the money and effort. However, if you have a bright student struggling with more advanced problems, it is simply a waste of money. I am sorry I bought it.

This definitely helped me out of a jam. I was taking Calc II without a strong background in Calc I. It was helpful but I would not rate this product as spectacular. The program was pretty worthless when it came to integrals with trig substitutions or any tough integrals. If you can get your hands on Maple 13, I would go for that. Maple 13 has a wonderful integral tutor! Overall, I felt like Calculus Solved was not advanced enough for Calc II.

I had a difficult time understanding pre-calc, so when I went on to Calculus, I thought I could use some extra help. But honestly, this program is not worth the money.

Mainly, there is a lot this program cannot do. For example, there are several symbols used in calculus that are not available on this program, including delta, which gets used often in calculus. So if Delta, or any of the others, appear in one of your complex functions, you are SOL.

You are also limited on your answering options. For example, if you need to "evaluate the difference quotient", too bad. You can solve for Y, you can solve for X, and you can graph it (provided you could enter in the problem in the first place), but that is about it.

I had high hopes that this program would help me learn Calculus, but because it is so limited, it can't even handle Chapter 1 of my book. I would not recommend spending the money for this program.

i bought this program to help through pre-calculus and into calculus. its main advantage was the ease with which one can enter problems -- no long command strings or tricky syntax to learn. most of the complex symbols are there and you just plug in the appropriate data into it.
the problem is that the translator (or whatever it is called) that creates the command string from your input, which is then passed to the command line interpreter to actually evaluate, make mistakes. for example: the composition of two functions works when you take fog; BUT, when you take gof, you get g(f(x)) instead of the composition. this is a pretty simple process and that it gets it wrong leads one to not trust the program for more complex processes.
yes, i did call technical support. they couldn't care less that the answer was wrong. they told me to enter it in command line syntax (which did work). HOWEVER, if i wanted to put things in a command line syntax, there are plenty of FREE programs out there to do that. what is going to happen when one has to enter a realllly complex problem (like during the third term of calculus or in linear algebra? if one cannot trust the answer one gets, the program is useless.
i now have maple, which works great. it is more complex to use, but works well for what i currently need. i can pick up the more complex stuff as i need it.

I thought I would just try out this program since the price was very affordable.

I was very surprised with the software. It does a great job on not-so complex calculus problems. For the beginner calculus student, or if you need a refresher, this software is very good. It shows you step by step to arrive to the answer. If the problem is too complex for the software to solve outright, you soon learn that you can solve the more complex problems merely by breaking the complicated problem down to smaller parts and solving the individual parts of the more complex problem, and simply combine the individual results. It also has a very good graphing capability that will automatically plot the function.

I believe it is a great buy.

If you're teaching or studying Calculus, you need this software.

You can:
Make your own practice tests
Enter a problem and see it solved step-by-step
Create and administer tests to students and keep track of their progress
Enter an equation and the program will graph it for you

I bought a license for most of the Bagatrix programs. As a parent, and as a premed student, I wouldn't be without them.

This product is great for calculus I and II. There were many students that had trouble with derivatives and integrals, and this product answered everything with all the steps.

My initial review was based on the fact that the program didn't work as advertised. After the latest update, it appears to be working - though I've tried very little.

To be fair to the software company I've traded my previous review with this one. The update hassle is what stopped me from rating it higher. I wish it had been released fully functional when I initially purchased it. However, it appears to have been addressed now after a few updates.

Sincerely,
AAA
